GASEMENT-WINDOH-ADJUSTMENT CONSTRUCTION;

Application filed February 24, 1926. Serial No. 90,364.

This invention relates to improvements in window constructions.

The primary object of this invention is the provision of a casement window ad ust ment construction, which will permit the removal or adjustment of the sash of the window construction.-

A further object of this invention is the provision of an adjustable mounting for casement windows by means of which the sash may be readily opened to various degrees for ventilation, or'be entirely removed with ease.

' Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein-similar reference characters designate correspon-ding parts throughout theseveral views,

In the drawing, wherein for the purpose of illustration is shown only apreferred embodiment of this invention, the letter A may generally designate the improved casement window adj ustinent construction, which may comprise a frame B within which the sash C is mounted for adjustment by means D.-

As is normally understood, the frame B is provided with an opening, within which the single casement sash C is'positioned toentirely fill the opening. It is a main objection of casement windows, thatthey cannot be. readily opened, nor the sashes removed, nor the same opened to various adjustments for ventilating purposes. I

The frame B is of course of any approved construction, and comprises the horizonal upper piece or yoke v1O; sill 1.1; and side stiles or pieces 12, which define theopening 13 adapted to receive the sash C. The yoke has. the conventional stop strip or head 15; and the side stiles or pieces 12 have vertical outer stop strips 16, to retain the sash C in position. The stool 18 is mounted in appropriate relation upon the sill 11, wit-h its rear edge in spaced relation with the in side surface of the stop beads 16 of the side stiles providing side recesses 19 justabove the sill 11, adapted to cooperate in detachably receiving reduced ends 20 of certain detachable adjusting strips which comprise part of the means D, and are'placed at each side of the opening 13 in movable relation with the side stiles12.

The sash C is of the type adapted to conform to the opening 13, having no sliding space within the opening 13. This sash C comprises the side rails 80 and 31; top rail 32 and bottomrail 33 supporting the pane of glass 34 therein.

The means D includes the adjusting strips 25, which as above mentioned are adjustably and detachably related to the side stiles or frame pieces 12 of the frame B. As illus-l trated in Figure 6 and elsewhere in the drawing, these adjusting strips 25 are preferably of one piece construction, although they 'may be formed other than of one piece. Each is preferably grooved inwardly of its window opening side to provide a channel 35.

- extending longitudinally of the strip 25; to

one side of the channel 35 providing a stop bead 36 which faces outwardly from the window sash, and at the opposite side providing a preferably beveled stop bead 37 which faces to the inside of the window sash, or faces inwardly of the room in which the casement window is provided. The body of the strip 25, along the channel 35 is provided with a-vertical series of spaced openings 38 therein, adapted to receive the shank 39 of a spring bolt arrangement lO'WhiCh is carried by the sash rail or rails 30 or 31, and which will be subsequently described, and whereby to connect the sash to the strips 25.

The lower end of each strip 25 is, as above mentioned, provided with the stepped end 20 adapted to be received in the recess 19 of the frame B; the end of the strip 25 being removed upwardly from the lower edge, along the stop bead 37, to provide the reduced portion 20, in order to provide a stay, so to speak, to maintain the strip 25 in place. Similarly, the upper end of the strip 25 is reduced, providing a shoulder 40, adapted to abut against the inside edge of the stop bead 15 of the yoke 10, in order to prevent the outward swinging of the shank supporting strip 25' with respect to the window opening 13.

Each of the strips 25 is preferably provided with a novel catch or retainer 42, including a leaf 43 hinged as at ll on the inside surface of the stop bead or portion 37 of the strip 25; the hinged piece 48 including an arcuate projection or detent 46, adapted to enter an opening 47 provided transversely thru the strip 25, upon which the retainer is hinged; and also to enter a socket 48 formed in the frame B, inwardly of the side member 12 thereof. Thus, with the catch 42 located on the strip 25 above the reduced portion 20, it is readily apparent that with the detent 42 locked in position, the strip 25 will be held in the casement opening against liability of accidental detachment until the retainer 43 is swung inwardly towards the casement opening, parallel with the plane thereof, in order to remove the detent 46 from its sockets a7 and i8, ascan readily be understood.

As an additional retainer to prevent lateral displacement of the strips 25, when the same are swung forwardly to position the sash in location to be opened, it'is preferred to provide substantially L-shaped brackets 50 on the stool portion 18 of the sill 11, which include upstanding flanges 51 adapted to abut against the lower portions of the stop beads 37 of the strips 25, as illustrated in Figures 1 and 4- of the drawing, in order to limit any inward movement of the strips 25, towards the window opening, and thus prevent lateral displacement thereof.

v The sash C has the rails 30 and 31 thereof slidably positioned in the channels 35 of the adjusting strips 25, so that it can be readily understood, upon forward tipping of the upper ends of the strips 25, into the room, to annularly position them at acute angle with respect to the window opening, the sash C may be readily moved upwardly to various degrees, for ventilating purposes. To this end, it is preferred to provide some means to retain or hold the lower ends of the strips 25, against falling movement into the room, and to hold the strips J3 at the desired angular relation. To this end, it is preferred to provide a novel friction catch 55, on each of the strips 25, whichincludes a plunger 56, mounted within a cylindrical casing 57, and urged by a spring 58, so that the head extension 59 thereof is normally forced toward the adjacent frame stile 12, for the purpose of entering a socket 60 of a wear plate 61 mounted on the frame side stile; the said plunger only so entering the socket 650 when the strips 25 are tipped forwardly at their upper ends, so that it can readily be understood with the reduced portions 20 held in position in the recess 19; the section catches 55 will limit the inward swinging of the strips 25, and prevent their overbalancing.

The strips 25 are so positioned that the sash C may be swung upwardly just suliiciently to miss the inside edge of the window frame B, at the yoke 10 thereof, as is illustrated in Figure 2 of the drawing.

In order to hold the sash C in the desired vertical adjustment with respect to the window opening and the strips 25, the spring bolts 40 are provided, as above mentioned; the same being slidably mounted in a horizontal relation in the lower portions 30 and 31 of the sash C. Each of these spring bolts 40 includes a hollow cylindrical casing 65, embedded inthe rail 30 or 31 of the same, as the ass may be; the plunger portion, of which the shank 39 isa part, being slidably mounted axial thru this casing 65, and urged by means of a spring 67 in the casing portion 65, so, that the shank 39 of this plunger is normally forced laterally toward the side stile of the window casing. lin fact, the shanks 39 are of'suflicient length to extend entirely thru the openings 38 of thestrips 25, and enter special sockets 70 provided therefor in the stiles 12, in order to lock the sash C, as well as the strips 25 in closed position in the window opening 13, against liability of detachment. The shanks 39 of the spring bolts do not enter the sockets 70 when the window sash is tipped inwardlyof the room, for ventilating adjustment,

As is illustrated in Figure 2, the sash C may be slid upwardlyand the spring bolts 30 at each side of the sash rails engaged in the desired openings 38 of the strips 25, in order to hold the sashC in a desired elevated and ventilated relation.

From the foregoing description of this invention it is apparent that a practical and simple type of casement window adjustment construction has been provided, by means of which small sashes for casement windows may be economically mounted for detachment and ventilating adjustment. From a closed position it is merely necessary to release the detent 42. The operator next grasps the handle portions of the plungers of the spring bolts 4C0, and draws the same inwardly to remove the shanks thereof from the sockets 70 of the frame B. The strips 25, together with the sash C may-then be swung bodily inwardly of the room, by

pivoting: the same at its lower ends, until the strips at their lower corners abutting against the inside surface of the stop beads 16 of the frame B, and in this position the friction catches 55 will engage at their plungers in the sockets 60, asillustrated in Figure 5 of the drawing, to hold the strips 25 in place against liability of forward tipping. The lateral displacement of the friction catches from their sockets 60 is prevented by reason of the flanges 51 of the brackets 50 above mentioned, and the sash C may be slid upwardly to any adjustment in the manner above described.

Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.
